Hehe, thanks. Yeah, the pic of the bird cracked me up. The scene of me shooting him should have been pretty funny too. I was chasing him and his buddy down the wall trying to get a decent shot. I was struggling with getting the right angle so as not to blow out the sky (which was hazy and whitish). I think he was looking at me like that thinking "what the heck are you doing you nutty ape?"
I used my EF 24-70mm f/2.8L USM for these shots. It's a great lens with lots of clarity and it works great with the extremely sensitive 50D sensor.
Hehe, I'm so picky I wind up filing many of the pics I take to DVD and deleting them from my HD.
I just got back from lunch where I ventured over to Navy Pier. I think I got some great shots of the 60 degree weather day. Once I get home I'll post some of them up.
